How many days after ovulation is it normal to have menstruation?

Many women want to get pregnant successfully. If they want to get pregnant, they have to pay attention to their ovulation. Of course, in order to know more clearly whether we are pregnant or not, we need to understand our menstruation after ovulation. In order to better understand this aspect of knowledge, we must first understand the issue of menstruation after ovulation. So, on which day after ovulation does menstruation come? Based on this question, we asked an authoritative expert to talk to you in detail about this issue.

1. Duration of ovulation period:

1. Generally speaking, a woman's ovulation period is 10 days.

A normal woman will ovulate once every menstrual cycle (usually once a month). The day of ovulation is called the "ovulation day". The 5 days before the ovulation day, the 4 days after the ovulation day, plus the ovulation day, are the woman's ovulation period. Therefore, women's ovulation period is 10 days.

2. Not everyone’s ovulation period is 10 days.

As the pace of modern life continues to accelerate, women are increasingly affected by the real environment. In addition, women's emotions, diet, lifestyle habits, etc. all affect their ovulation. When a woman with a relatively regular rhythm of life suddenly changes her living habits, if the body does not adjust in time, the endocrine system may be affected, and the menstrual period may be advanced or delayed. Then the length of the ovulation period will fluctuate with the changes in the menstrual period. Therefore, the 10-day ovulation period is only an approximate time range, and in fact, a woman's ovulation period is generally less than 10 days.

3. The effective conception time during the ovulation period is 7 days.

Since the ovulation period is not necessarily a fixed ten days, how long is the effective pregnancy time if you have sex during the ovulation period? Generally speaking, the survival time of a normal woman's egg is about 2 days, up to 3 days, and less than 12 hours. A man's sperm can generally survive in a woman's body for 3 to 5 days, usually 4 days.

In other words, the effective conception time during the ovulation period is generally 5 days before female ovulation, because sperm can survive in the female body for up to 5 days, and 2 days after female ovulation, because the egg can only survive in the female body for 2 days after being released. In other words, the effective conception time is generally about 7 days.

2. When is ovulation?

1. If the menstrual cycle is regular, a woman's ovulation period is generally about 14 days before the next menstrual period. The 5 days before and 4 days after ovulation, together with the ovulation day, a total of 10 days are called the ovulation period.

2. If your menstrual period is unstable, your ovulation period can be calculated as follows: the first day of ovulation = the shortest menstrual cycle minus 18 days, the last day of ovulation = the longest menstrual cycle minus 11 days. The calculation method is to take the first day of menstruation as the base point and count the days backwards.

For example, if your menstrual cycle is irregular, sometimes it is only 23 days, and sometimes it is as long as 35 days. Then the first day of your ovulation period is 23-8=5, and the last day of your ovulation period is 35-11=24. In this case, the ovulation period may be as long as 24-5=19 days. However, this only means that there is a possibility of ovulation during this period, and it is impossible to accurately calculate the exact day of ovulation.

How many days after ovulation does menstruation come? The above is what the experts introduced. For women with regular menstruation, the ovulation calculator is more accurate in calculating the ovulation period. However, if a woman's menstrual cycle is irregular, with delayed or early menstruation, the calculated ovulation period will be biased. And because a woman's ovulation day will change due to external conditions, for women with irregular menstruation, the most accurate method is to go to the hospital to monitor ovulation in order to accurately grasp the ovulation period.
